Clashing Measurements
Make the Universe's Expansion a Lingering Mystery (Source:
Scientific American)
How fast is the universe expanding? One might assume scientists long
ago settled this basic question, first explored nearly a century ago by
Edwin Hubble. But right now the answer depends on who you ask.
Cosmologists using the Planck satellite to study the cosmic microwave
background—light from the “early” universe, only about 380,000 years
after the big bang—have arrived at a high-precision value of the
expansion rate, known as the Hubble constant (H0).
Astronomers observing stars and galaxies closer to home—in the “late”
universe—have also measured H0 with extreme precision. The two numbers,
however, disagree. According to Planck, H0 should be about 67—shorthand
for the universe expanding some 67 kilometers per second faster every
3.26 million light-years. The most influential measurements of the late
universe, coming from a project called Supernova H0 for the Equation of
State (SH0ES), peg the Hubble constant at about 74.
This discrepancy—the so-called Hubble tension—has been growing for
years, increasing as study after study of both the early and late
universe yield ever more precise results and leave scientists on both
sides anxious and bewildered. After all, it could be that either
faction is somehow just mismeasuring the universe. But the tension may
be a true reflection of reality, requiring exotic new physics and a
dramatic revision to our understanding of cosmic evolution. (7/29)
Why Space Agencies,
Companies World Over are Looking to Mars as the Next Frontier
(Source: FirstPost)
The interest in Mars is more than just scientific. There are currently
people working on trying to establish a permanent human colony on Mars.
The logic of this is as follows. Mars is the closest to earth in terms
of its environment. It has an atmosphere, albeit one that is made up
almost completely of carbon dioxide. And it has a 24 and a half hour
day, almost the same as earth. Then it is about half the size of earth
and so it has a gravity that will be familiar to us, though it is less.
Someone weighing 50 kilos on earth will weigh less than 20 kilos on
Mars.
The other planets of our solar system are very different from earth.
They are very far away from the sun and therefore are very cold, some
like Jupiter are huge and with gravity that is very high and some have
atmospheres that are poisonous.
Mars also has plenty of water in ice form. And because it has carbon
dioxide, it is possible to make hydrocarbons, meaning plastics, from
the materials already available there. The other big issue of space
travel is that of fuel, and there are rockets being designed today that
will be powered by methane and liquid oxygen, both of which can be
produced on Mars. (7/28)
Next Generation Space
Suit Being Designed for Extended Trips (Source: Hartford
Courant)
United Technologies Corp. and a Delaware space systems manufacturer
have introduced their newest space suit for extended trips as the U.S.
prepares for an eventual Mars mission. Collins Aerospace, a unit of
UTC, and ILC Dover of Frederica, Del., unveiled the Next Generation
Space Suit system prototype at a Capitol Hill event in Washington,
D.C., Thursday.
The two companies funded and designed the space suit system with NASA
and commercial customers in mind, including lunar surface missions in
partial gravity, orbital space station missions and “future planetary
missions.” It features new ways to remove carbon dioxide regenerated
while in use, allowing missions of extended duration and reducing
dependency on resupply and cutting crew maintenance time.
The new space suit improves mobility at the body’s joints. The lower
torso is designed to improve walking to allow astronauts to navigate
hazardous terrain, perform difficult assembly tasks and examine, handle
and collect geological samples from the surface. The suit also includes
advanced sizing features for more astronauts to have the best fit in as
few as two sizes. (7/26)

Cape Canaveral Launch Complexes Before They Slip Into the Sea
(Source: TampaBay.com)
The launch complexes at Cape Canaveral have seen better days. The metal
beams that helped send the first American into orbit have corroded from
salty air. Hurricanes and rising sea levels have carved out escarpments
and erased sand dunes. At Launch Complex 34, the encroaching shoreline
has not yet reached the launch pad but has reached places where fuel
tanks and trucks used to be during the Apollo era. Along the nearby
Banana River, the cemeteries of the Cape’s first settlers are eroding
away.
It will be 20 to 25 years until the ocean reaches all of the launch
complexes, said Tom Penders, the 45th Space Wing's cultural resources
manager. But he isn’t panicking. The buildings will live on, not only
in memory but also digitally in 3D and sub-millimeter detail put
together by laser scanners. For the past five years, Lori Collins and
Travis Doering, co-directors of the Digital Heritage and Humanities
Collections at the University of South Florida Libraries, have been
traveling with a team to Cape Canaveral to collect detailed information
about launch complexes and buildings. (7/29)

Nine students have been inducted into the Space Coast Consortium
Apprenticeship Program, making its inaugural class. The SCCAP is an
industry-driven apprenticeship program created in direct response to HB
7071, which relates to workforce education. Manufacturing companies
including OneWeb Satellites, RUAG Space, Rocket Crafters, and Knights
Armament are leading the way in the apprenticeships. The program is
registered with the Florida Department of Education and will be led in
partnership with Eastern Florida State College. The two-year
apprenticeship program will develop mechatronics technicians, fiber
composite technicians, and advanced CNC/DNC machinists.
The consortium approach to the apprenticeship program is the first of
its kind in Florida and comes only weeks after Governor DeSantis
visited the Space Coast to sign CS/HB 7071, a broad workforce education
bill that includes a number of provisions enhancing apprenticeship
programs in Florida. The consortium was formed in 2017 by Kai Schmidt,
Human Resources Director of OneWeb Satellites and Bryan Kamm, Founder
and Principal of Kamm Consulting, to address a shortage of highly
skilled advanced manufacturing workforce on the Space Coast. (7/29)
NASA Fed Some of its
Precious Apollo 11 Lunar Samples to Cockroaches (Source:
CNN)
Scientists from NASA had a lot more leeway to conduct weird experiments
50 years ago, which included feeding moon dust to German cockroaches.
But it didn't stop there. Astronauts Neil Armstrong and Buzz Aldrin
were able to secure lunar samples from the surface of the moon from the
Apollo 11 mission and bring them back to Earth. However, in order to
ensure that it was safe to store lunar samples on Earth, scientists had
to run a number of tests to make sure contamination was not possible,
according to NASA.
Armstrong and Aldrin were quarantined for weeks on their return from
the moon, and they had a few extra roommates: mice that had been
injected with lunar material. "They always wanted to know how the
rodents were doing," Judith Hayes, chief of NASA's Biomedical Research
and Environmental Sciences division, told Space.com. "If the rodents
did well, then they would likely be released on time, if the rodents
weren't well, they would likely be examined much more carefully and
longer."
NASA also chose a number of different animals to represent other
species. Birds were represented by Japanese quail; brown shrimp, pink
shrimp and oysters were used to represent shellfish; houseflies and
moths joined the cockroaches to represent insects; and guppies and
minnows were used to represent fish. As for how they all received the
samples, it varied. The quail and mice received injections, moon dust
was added to the water for all the aquatic species and the insects had
lunar samples mixed into their food. (7/29)
Planet-Hunting Satellite
TESS Finds 'Missing Link' Exoplanets (Source: CNN)
NASA's planet-hunting satellite TESS has discovered more than 20
exoplanets during its first year of observations, including some
"missing link" planets entirely unlike anything in our own solar
system. TESS, which stands for Transiting Exoplanet Survey Satellite,
began science operations in space in July 2018. TESS focused on the
southern skies for the first year and will turn to the Northern
Hemisphere for an ambitious observation campaign over the next year.
And the new star system may harbor planets within the habitable zone,
in which the temperature on a planet's surface is just right to support
liquid water and potentially life. The newly discovered exoplanets are
some of the smallest and closest ever found. The three worlds, which
include a rocky super-Earth and two sub-Neptunes, orbit a star just 73
light-years from Earth. Sub-Neptunes are smaller than the icy gas giant
in our solar system. These two are about half the size of Neptune.

Synspective is planning a constellation of around 25 small SAR
satellites for global coverage of the Earth, with its first satellite,
a 150-kilogram demonstrator, slated to launch on an Arianespace Vega
rocket in 2020. By 2022 the startup hopes to have six satellites in
orbit, enabling sufficient imaging capacity to cover all of Asia’s

ESA Invites Industry
Concepts for 2026 Mars Sample Return (Source: Space News)
Plans to return samples from Mars are taking shape at NASA and ESA,
although formal approval and funding is still pending. ESA released
last week an invitation to tender to industry for a proposed orbiter
that would launch in 2026 to go to Mars and collect samples placed in
orbit by a NASA mission for return to Earth in 2031. NASA, meanwhile,
held an acquisition strategy meeting earlier this month about the
proposed Mars sample return campaign, giving approval to move into
budget development for NASA's contributions to the mission and to
continue cooperation with ESA. The two agencies have yet to commit to
funding for their roles in a Mars sample return effort, with ESA
expected to decide whether to fund the orbiter and other contributions
at its ministerial meeting in November. (7/29)

India to Begin First-Ever
Simulated Space Warfare Exercise (Source: Sputnik)
The Indian military plans to begin a two day first-ever simulated space
warfare exercise on 25 July to draft a joint military space doctrine to
secure outer space assets. "There is a need to explore effective
tactical, operational and strategic exploitation on the final frontier
of warfare. We cannot keep twiddling our thumbs while China zooms
ahead. We cannot match China but must have capabilities to protect our
space assets," an official said while providing the rationale behind
conducting such a drill.
The drill is being held four months after India joined the select group
of nations having the capability to shoot down a satellite with their
ballistic missiles. The tri-service command of the Indian military will
monitor the trials dubbed "IndSpaceEx" on Andaman Island in the Bay of
Bengal. In May, the Indian military initiated the formation of
