Scientists Want to Build a Doomsday
Vault on the Moon (Source: CNN)
Engineers want to build an underground lunar ark, filled with millions
of seed, spore, sperm and egg samples from Earth's species, hidden in a
network of tubes on the moon to provide a genetic backup for the planet
in the event of a doomsday scenario. Scientists from the University of
Arizona have proposed an ark, dubbed a "modern global insurance policy"
for 6.7 million species from Earth, cryogenically preserved and hidden
inside a series of caves and tunnels under the moon's surface.
They said the vault could protect the genetic materials in the event of
"total annihilation of Earth" which would be triggered by a major drop
in biodiversity -- but any move to build such a bunker is a long way
off. Similar "doomsday vaults" exist on Earth: The Global Seed Vault,
home to just under 1 million seed samples, is located on a remote
island in Svalbard, an archipelago located between Norway and the North
Pole. (3/16)
NASA Announces Lunar Delivery
Challenge Winners (Source: NASA)
With the Artemis program, NASA will send the first woman and next man
to the surface of the Moon, construct a lunar orbiting outpost, and
establish a sustainable presence. This will require deliveries of
supplies and equipment to the lunar surface, but how to unload the
cargo once it arrives is an open question. NASA created the Lunar
Delivery Challenge to seek ideas from the public for practical and
cost-effective solutions to unload payloads onto the surface of the
Moon.
The challenge received 224 entries before the submission period closed
Jan. 19, 2021. The ideas came from various types of space enthusiasts
who share a passion for human space exploration, and participants
varied from student teams, to individuals from the private sector, to
parent-child duos. NASA awarded $25,000 in total prizes to six teams,
including one first place winner with a prize of $10,000; two second
place winners with prizes of $4,500 each; and three third place winners
with prizes of $2,000 each. Click here.

From the Pandemic to Going Public:
Space Startups Face Hiring Challenges (Source: Space News)
Isotropic's U.S. office is located in Maryland, amid office parks
between Washington and Baltimore filled with aerospace and defense
contractors. “We are competing for the best engineers from some of the
biggest players out there,” he said, noting that the company is next
door to a Northrop Grumman facility. “It’s a matter of attracting
people that want to come and do something new.”
That challenge is magnified when you’re not able, or at least willing,
to talk publicly about what you’re doing. In its first few years, small
launch vehicle developer Astra kept a low profile, without a public
website or other discussion. The company called itself “Stealth Space
Company” in its online job listings. "We worked really hard to bring
people in here,” Chris Kemp, co-founder and chief executive of Astra,
said in an interview of those early hiring efforts. “But we literally
had to bring people in here and show them the place.”
Private companies can still attract talent from publicly traded firms.
Commercial imaging company Satellogic announced Feb. 11 it hired a
former Maxar executive, Thomas VanMatre, as its vice president of
global business development. He held a similar position at Maxar.
Satellogic, which is just starting to build out its constellation of
high-resolution imaging satellites, has an unusually global presence
for a company of its size, with offices in the United States, Latin
America, Israel and China, tapping local expertise in software,
satellite manufacturing and business development. The company has more
than 200 employees now, and he said he expects to hire 70 people in
this quarter. (3/11)
SpaceX Bid on Launch of NASA Cubesat
Mission (Source: Space News)
A NASA competition to launch a cluster of TROPICS cubesats attracted a
bid from SpaceX, who appeared to offer a vehicle other than its current
Falcon 9 or Falcon Heavy. NASA awarded a contract for the launch to
Astra Feb. 26, valued at $7.95 million. The agency said in the
statement that it received five proposals last August for the mission.
Besides Astra, two other small launch vehicle companies, Rocket Lab and
Virgin Orbit, submitted bids.
A fourth bid came from Momentus, which offers in-space transportation
services for satellites launched on rideshare missions. The fifth bid
came from SpaceX, which has a smallsat rideshare program, bundling
groups of cubesats and other small satellites on Falcon 9 launches.
However, the company did not appear to offer launch services with that
vehicle. In its assessment of the bidders, NASA noted a weakness in
SpaceX’s proposal because the company “did not clearly demonstrate
progress toward the resolution of the environmental assessment which
results in risk associated with obtaining an FAA launch license.
An intriguing possibility is that SpaceX instead offered its Starship
vehicle under development. That vehicle has an FAA launch license today
only for its current series of suborbital test flights. The FAA is also
performing an environmental assessment of SpaceX’s Boca Chica, Texas,
site for orbital launches of that vehicle. (3/16)

Return of Pegasus: Air-Launch Rocket
Selected for Responsive Launch Demo (Source: SpaceFlight Now)
The U.S. Space Force is planning for an airborne launch of a
solid-fueled Pegasus rocket over the Pacific Ocean by early summer
after quietly awarding Northrop Grumman a contract for the mission last
year. The Pegasus rocket is an air-launched vehicle designed to drop
from the belly of Northrop Grumman’s L-1011 carrier jet, then fire
three solid-fueled rocket stages to place small satellites into orbit.
The TacRL-2 mission later this year will use a Pegasus rocket staged
out of Vandenberg Air Force Base, California. The mission is part of
the Space Force’s “Tactically Responsive Launch” program. “That’ll be a
great test for our team to hone the skill required to launch on demand
and with agility,” Col. David Rickards said. “Said more plainly, we’ll
be given a short window of just three weeks to generate, to deploy, and
execute a real world launch." (3/17)
FAA Approves Plans for Pegasus
Air-Launches From Virginia, Florida (Source: FAA)
After completing a comprehensive review, the FAA approved the renewal
of two Launch Operator Licenses for Orbital Sciences, LLC, a subsidiary
of Northrop Grumman. The licenses are valid for five years and
authorize the company to conduct flights of its Pegasus launch vehicle
from the Wallops Flight Facility in Virginia and the Cape Canaveral
Space Force Station in Florida. Orbital Sciences must still receive FAA
authorization for specific launches. The Pegasus operates by being
attached to a carrier aircraft and launched while airborne to deliver
payloads to low earth orbit. (3/17)
Wormholes Across The Universe Are
Fully Traversable, New Calculations Show (Source: Universe Today)
Wormholes are an old idea in general relativity. It's based on work by
Albert Einstein and Nathan Rosen, who tried to figure out how
elementary particles might behave in curved spacetime. Their idea
treated particle-antiparticle pairs as two ends of a spacetime tube.
This Einstein-Rosen Bridge would look like a black hole on one end, and
an anti-black hole, or white hole, on the other end. The particle
physics idea never panned out, but work inspired other researchers to
study ER-bridges as a possible shortcut through space.
If wormholes were traversable, you could burrow through spacetime like
a worm burrowing a hole through an apple. It didn't take long for
theorists to discover this wouldn't work. Although wormholes are valid
solutions to Einstein's equations, they collapse so quickly you'd never
have time to go through them. Of course, impossibility never stops a
persistent theoretician, and soon they figured out you could make a
wormhole traversable by lining it with some kind of negative energy.
But matter with negative mass/energy doesn't seem to exist. However, we
know that Einstein's theory must break down at quantum scales.
Presumably, there is some quantum theory of gravity that supplants
general relativity.
One of these models is known as the Einstein-Dirac-Maxwell theory. It
includes aspects of Einstein's theory of gravity, Maxwell's theory of
electromagnetism, and Dirac's theory of quantum particles. Recently a
team found a wormhole solution to the Einstein-Dirac-Maxwell equations.
What's more, the solution doesn't require any negative-energy states.
In principle, that would allow you to travel through the wormhole
without needing negative mass. The only catch is that you would need to
be in a quantum state. So microscopic clumps of atoms could travel
through this wormhole, but not people. (3/6)
Alan Stern: Building Back Better in
Space (Source: The Hill)
Recent Democratic presidents have supported and initiated important,
bold and sustainable robotic and commercial space efforts. But no
Democrat since John F. Kennedy has set this nation onto a course that
resulted in humans exploring new worlds. I am a scientist whose career
has been organized around and benefited tremendously from robotic space
exploration. Yet I can say with authority that no robotic space
exploration mission has ever had such a powerful and pervasive impact
as Kennedy sending Americans to explore another world.
Kennedy’s bold vision propelled science forward greatly. President
Biden was first elected to the Senate during Apollo. To his credit, the
president has already affirmed that his administration will continue
NASA’s Artemis program to send the first woman and the next man to the
Moon. Moreover, Biden has signaled his innate grasp of what Kennedy’s
Apollo accomplished and how space exploration can inspire on a larger
scale. But where will Biden take this nation in human space
exploration? How can he brand his administration to be both as bold and
effective in space as Kennedy’s administration was?
As with other Biden initiatives, like his Cancer Moonshot and green
energy future, he can use space to inspire. In this daunting,
pessimistic and divided time we may actually need space initiatives
more today than even in the darkest days of the Cold War. Biden should
craft our human space exploration to project bold U.S. global
leadership by sending men and women to do more than just visit, but to
establish bases on these new frontiers. In doing so, he would no doubt
launch a powerful new wave of science and engineering careers to fuel
the nation’s tech economy for decades to come. (3/15)
Space Force: Government Could Pay for

capabilities, but Thompson said he was not familiar with them. (3/17)
Arsenic and (Very) Old Life (Source:
Air & Space)
Based on studies of Mono Lake in California, we already knew that
microbes can metabolize arsenic. But that was generally thought to be a
very special adaptation of bacteria to extreme conditions in an unusual
soda lake. That view is now changing very quickly, following a 2019
study supporting the idea that the biological use of arsenic is not
only intended to lessen its toxicity, but also to gain metabolic
energy. The study showed that some microbes use arsenic for respiration
in the open tropical ocean, in places where there is no available
oxygen.
An earlier assertion that some microbes may prefer arsenic over
phosphorous for growth and substitution in their DNA has largely been
refuted. Nevertheless, it seems that using arsenic to gain critically
needed energy is not only a way for life to gain a foothold in niche
environments like Mono Lake, it may have been very important for early
life on Earth. The same should hold true for life in any
oxygen-depleted natural environment, including Mars. (1/29)
Satellite Operators Want Seat at the

Satellite operators want to participate in discussions about rules of

safe operations in space is vital to their businesses. Discussions
about a potential agreement to codify norms of behavior in space need
to address not just space-based threats, he said, but also the
ground-based infrastructure that controls satellites. (3/17)
Aerojet Rocketdyne Not Concerned About
Potential Artemis Changes (Source: Space News)
An Aerojet Rocketdyne executive said his company is not concerned about
any potential changes to NASA's Artemis program. Aerojet CFO Dan Boehle
said he did not expect any changes in the program, such as delaying a
human return to the surface of the moon until later in the decade, to
have a "material impact" on his company's work, which includes
supplying RS-25 engines for the Space Launch System.
The growth of the RS-25 program has helped the company offset losses
elsewhere, such as the end of AJ-60 solid rocket motor and RS-68 engine
programs. Boehle said that, if its acquisition by Lockheed Martin is
approved later this year, Aerojet remained committed to being a
merchant supplier of propulsion systems to other companies, including
those competing with Lockheed. (3/17)
Democrats Ask Biden to Cut Defense

A group of congressional Democrats is asking the Biden administration
to cut defense spending. The letter from 50 Democratic members of
Congress Tuesday asked the White House to shift defense spending to
areas ranging from global public health to diplomacy. How those cuts
would be made isn't clear, but one analyst expected the Space Force
would not be affected much, in part because it is a small fraction of
overall defense spending. The administration is reportedly planning a
fiscal year 2022 budget proposal for the Defense Department that would
keep spending at the same level as 2021. (3/17)

Hydrated Minerals Trap Water in Mars

A quest by scientists to follow the water on Mars may lead them
underground. In a study published Tuesday, scientists said they believe
much of the water that existed on the planet's surface early in its
history is now trapped in hydrated minerals in the planet's crust,
rather than lost to space. Scientists said the rate at which water is
lost to space from the planet's atmosphere can't account for more than
a small fraction of the water Mars once had. Research concluded that
between 30% and 99% of that original water is locked up in minerals
buried below the surface. (3/17)

The Space Tourism Market Is Heating
Up... But When Will It Happen? (Source: Forbes)
Virgin Galactic is shifting their executive team around to get ready
for paid passengers. Blue Origin keeps quietly testing in the
stratosphere above West Texas. Two new contests – Inspiration4 and
#dearMoon – both promise the chance to win your spot on an
out-of-this-worth adventure. A new space hotel is announced at least
once per year. Oh, and Elon Musk’s SpaceX team keep drawing hundreds of
thousands of eyeballs to livestreams documenting the steady march of
progress for Starship – the craft that will eventually carry humans to
Mars.
Space has never felt so close, yet so far away. After dedicating myself
to the space tourism industry back in 2017, I’ve been patiently waiting
for actual space tourism – like so many of you. But it’s not hard to
understand if your patience is wearing thin, especially when each new
announcement comes with an overly ambitious timeline that will
inevitably let us down. “Companies should try to not overpromise.
Hyping up unrealistic plans is a good way to create a cynical customer
base,” said Laura Seward Forczyk. “Instead, companies should be honest
with customers and emphasize their focus on flying when it's safe.”
There are obviously several benefits to committing to a specific year,
increased public interest and media exposure being chief among them.
However, publishing overly ambitious – one might even say unrealistic –
launch timelines can end up hurting the mission in the long run. Just
think back on how many space hotels should have been launched by this
point. From the grand ambitious of space hotels to the cautious
slow-moving Blue Origin, every space tourism timeline has slipped,”
concludes Seward Forczyk. (3/15)
