Starship Faces Performance Shortfall
for Lunar Missions (Source: America Space)
NASA understood that it was accepting a degree of risk when it selected
Starship as the solitary lunar lander design for Artemis 3 and 4. The
only alternatives were an overweight Dynetics lander and a Blue Origin
lander which would need a substantial redesign to achieve NASA’s
long-term goal of landing four astronauts on the Moon. In this context,
Starship had significant upside, as it far exceeded the HLS performance
requirements.
SpaceX claimed that it could deliver 100 tons of cargo to the lunar
surface, which would reduce the operating costs of the Artemis Base
Camp. In addition, SpaceX’s $2.9 billion bid was half the price of its
competitors’ landers, since the company could offset Starship’s
development cost by also utilizing it to launch satellites. However,
its ability to reach the Moon was cast into doubt by an announcement by
Elon Musk two weeks ago.
The most important part was arguably contained within one
sentence: “Currently, Flight 3 would be around 40-50 tons to
orbit.” Prior to this, Starship’s estimated payload capacity had ranged
between 100 and 150 tons to LEO. The most straightforward
interpretation of Musk’s comment is that the rocket is suffering from a
50% underperformance. SpaceX is already designing an upgraded “Starship
2.” Both stages of the rocket will be slightly longer and they
will feature the improved Raptor 3 engine. (4/19)
Starship Will Be 500 Feet Tall for
Mars Missions, Elon Musk Says (Source: Space.com)
SpaceX's Starship, the largest rocket in the world, will get even
bigger as the company continues to target Mars missions in the future.
Elon Musk, the billionaire founder of SpaceX, told employees on April 4
that Starship will eventually be as tall as 500 feet (150 meters),
roughly 20% higher than the massive system aboard the Super Heavy
rocket right now.
What's more, advances in reusability will have each launch cost roughly
$3 million each, Musk predicted; that's less than a third of what a
(much smaller) Falcon 1 rocket launch cost in 2004 when inflation is
taken into account. (The figure two decades ago was $5.9 million,
according to NBC, which is roughly $9.5 million in 2024 dollars.) (4/13)
Startups Want to Cool Earth by
Reflecting Sunlight. There Are Few Rules and Big Risks (Source:
NPR)
In the past year, the conversation around solar geoengineering as a
climate solution has become more serious, says David Keith, geophysics
professor and head of a new University of Chicago initiative to study a
broad array of climate geoengineering ideas. "Suddenly we're getting
conversations with senior political leaders and senior people in the
environmental world who are starting to think about this and engage
with it seriously in a way that just wasn't happening five years ago,"
Keith says.
But as money flows in – some from investors who hope to profit from
this technology – regulations around outdoor experiments and possible
broader deployments aren't keeping up, experts say. Because of the way
the stratosphere works, a large-scale release of particles in one part
of the world could impact a large part of the planet. Questions persist
about possible risks of solar geoengineering for everything from global
crops to droughts. And there are risks of unintended consequences that
scientists and investors haven't yet imagined – the unknown unknowns of
trying to engineer a cooler Earth. Click here.

Are We Prepared for Chinese
Preeminence on the Moon and Mars? (Source: Space.com)
The rate at which the Chinese have been catching up is alarming.
According to a 2022 Pentagon report, the U.S. could lose its lead in
space technology as soon as 2045. The report notes that, while U.S.
industrial capacity is expanding, "the upward trajectory of the
People's Republic of China…is even steeper, with a significant rate of
overtake, requiring urgent action."
The report added that "the U.S. lacks a clear and cohesive long-term
vision, a grand strategy for space that sustains economic,
technological, environmental, social and military (defense) leadership
for the next half century and beyond." With so many other major
national issues that hold center stage, the Administration and Congress
also do not appear to be appropriately focused and motivated in what
truly constitutes the new Space Race. Stable bipartisan support
remains, but we seem to lack a sense of national urgency. (4/22)

How Rocket Lab Outgrew Billionaire
Elon Musk's Space Company in Q1 (Source: Motley Fool)
Rocket Lab stock is on a tear. Over just the past week, Rocket Lab has
announced a $32 million U.S. Space Force contract to put a "VICTUS HAZE
Tactically Responsive Space" satellite in orbit. Another Space Force
contract will see Rocket Lab launch a DISKSat into very low earth orbit
for $14.5 million. The company plans to reuse one of its Electron
first-stage rockets in an orbital launch for the first time ever.
You might not guess it from the stock price (which is down 13% since
the end of March), but all of the above follows Rocket Lab's
announcement that it launched its 46th successful mission in March, and
is planning to launch No. 47 later in April. As Rocket Lab gears up to
report its financial results for first-quarter 2024 on May 6, the
company clearly has some momentum. But the truth is even bigger than
that: Rocket Lab is now growing faster than SpaceX. (4/22)
Astronomers Find Evidence Of A Massive
Object Beyond The Orbit Of Neptune (Source: IFL Science)
Ateam of researchers say they have found the "strongest statistical
evidence yet that Planet 9 is really out there" in the solar system
after studying a population of distant, unstable objects that cross
Neptune's orbit.
When it comes to discovering planets, finding them around other stars
is actually a little easier than locating them around our own.
Astronomers can watch for dips in light as planets pass their host star
and block the light reaching our telescopes on Earth or in space, known
as the "transit method"; or by observing the wobble of a star caused by
planets orbiting it and the knock-on effect that has. Through these
methods, and a few others, we have discovered thousands of exoplanets
in the last few decades, while the number of planets in our solar
system has remained at eight. (4/22)
Work Underway on Large Cargo Landers
for NASA’s Artemis Moon Missions (Source: NASA)
Under NASA’s Artemis campaign, the agency and its partners will send
large pieces of equipment to the lunar surface to enable long-term
scientific exploration of the Moon for the benefit of all. NASA’s human
landing system providers, SpaceX and Blue Origin, are beginning
development of lunar landers for large cargo deliveries to support
these needs.
NASA has contracted SpaceX and Blue Origin to provide landing systems
to take astronauts to the Moon’s surface from lunar orbit, beginning
with Artemis III. The agency has asked the two companies to develop
cargo versions of their human lunar landers as an option under their
existing contracts. These cargo variants are expected to land
approximately 26,000 – 33,000 pounds (12 to 15 metric tons) of payload
on the lunar surface and be in service no earlier than the Artemis VII
mission. (4/19)
NASA Still Investigating Orion Heat
Shield Issues from Artemis 1 Moon Mission (Source: Space.com)
Earlier this year, NASA announced it had delayed until September 2025
the crewed Artemis 2 swingby of the moon, a practice run to prepare for
2026's Artemis 3 mission, which will land astronauts near the lunar
south pole. One reason cited for the 10-month delay was getting to the
bottom of reentry heat shield data from Artemis 1, which sent an
uncrewed Orion capsule to lunar orbit and back.
Engineers have been analyzing data from that shakeout cruise, which
began with a launch by NASA's Space Launch System megarocket on Nov.
16, 2022. The 25-day Artemis 1 mission ended on Dec. 11, 2022, with the
Orion capsule splashing down under parachutes in the Pacific Ocean off
Baja California.
Orion's heat shield took on the 25,000 mph (40,000 kph) reentry speed
that day, protecting the capsule ably. But soon thereafter, NASA and
contractors began wrestling with the discovery that Orion's ablative
heat shield wore away differently than predicted. Some areas of
expected charred material ablated away in a manner not forecast by
computer modeling and ground testing. Also, there was slightly more
liberation of the charred material during reentry than anticipated.

NASA is continuing efforts to respond to a decadal survey that set
