You Can’t Take the Sky
From Me (Source: Space Review)
Plans by SpaceX and other companies to deploy megaconstellations of
satellites have alarmed astronomers, who worry that such satellites
could interfere with their observations. Arwen Rimmer argues that such
satellites should be a concern to anyone who looks up into the night
sky, not just professional astronomers. Click here.

A Mars Sample-Return
Mission is Coming. Scientists Want the Public to Know What to Expect
(Source: Space.com)
The first pristine pieces of Mars won't be coming down to Earth for at
least another decade, but the time to start preparing society for the
epic arrival is now, scientists say. NASA's 2020 Mars rover is
scheduled to launch in July of this year and land inside the Red
Planet's 28-mile-wide (45 kilometers) Jezero Crater next February. The
six-wheeled robot will do a variety of work once it gets there, but its
headline task is hunting for signs of ancient Mars life.
Mars 2020 will do this on the ground in Jezero, which hosted a lake and
a river delta billions of years ago. The rover will also collect and
cache promising samples for eventual return to Earth, where scientists
in well-equipped labs around the world can scrutinize them in exacting
detail for any evidence of Martian organisms. (1/13)
Spaceships Don’t Go to
the Moon Until They’ve Gone Through Ohio (Source: NASA)
From the South, to the Midwest, to infinity and beyond. The Orion
spacecraft for Artemis I has several stops to make before heading out
into the expanse, and it can’t go to the Moon until it stops in Ohio.
It landed at the Mansfield Lahm Regional Airport on Nov. 24, and then
it was transferred to Plum Brook Station where it will undergo a series
of environmental tests over the next four months to make sure it’s
ready for space. The 40-degree-and-extremely-windy weather couldn’t
stop the massive crowd at Mansfield from waiting hours to see the Super
Guppy land.
Families huddled together as they waited, some decked out in NASA gear,
including one astronaut costume complete with a helmet. Despite the
delays, about 1,500 people held out to watch the bulbous airplane touch
down. After Orion safely made it to Ohio, the next step was
transporting it 41 miles to Plum Brook Station. It was loaded onto a
massive truck to make the trip, and the drive lasted several hours as
it slowly maneuvered the rural route to the facility. The 130-foot,
38-wheel truck hit a peak speed of about 20 miles per hour. It was the
largest load ever driven through the state, and more than 700 utility
lines were raised or moved in preparation to let the vehicle pass.

Washington National
Cathedral dedicates Bible for newly formed U.S. Space Force
(Source: Washington Post)
Religious leaders blessed a King James Bible at Washington National
Cathedral on Sunday to be used by the newly formed United States Space
Force, including for swearing-in ceremonies, a cathedral spokeswoman
said. During the three-minute ceremony, the Right Rev. Carl Wright, the
Episcopal Church’s bishop suffragan for the Armed Forces and Federal
Ministries, said in part: “May this Bible guard and guide all those who
purpose that the final frontier be a place where God will triumph over
evil, where love will triumph over hate, and where life will triumph
over death.”
The ceremony also was overseen by the Very Rev. Randolph Marshall
Hollerith, dean of Washington National Cathedral, and Maj. Gen. Steven
A. Schaick, chief of chaplains for the U.S. Air Force. The Space Force,
the sixth branch of the U.S. military, was created in December as part
of a defense bill signed by President Trump. The force is designed to
defend American interests in space, such as satellites used for GPS,
communications and missile defense. The Bible was donated by the Museum
of the Bible in Washington. (1/12)
Mars Loses Its Water Even
Faster Than Anyone Thought (Source: Space.com)
Water might escape Mars more effectively than previously thought,
potentially helping to explain how the Red Planet lost its seas, lakes
and rivers, a new study finds. Although Mars is now cold and dry,
winding river valleys and dry lake beds suggest that water covered much
of the Red Planet billions of years ago. What remains of the water on
Mars is mostly locked frozen in the Red Planet's polar ice caps, which
possess less than 10% of the water that once flowed on the Martian
surface, prior work has suggested.
Previous research has also indicated that Martian water mostly escaped
into space. Ultraviolet radiation from the sun breaks apart water in
Mars' upper atmosphere to form hydrogen and oxygen, and much of this
hydrogen then floats off into space, given its extraordinarily light
nature and Mars' middling gravity (which is just 40% as strong as
Earth's). Recent findings suggested that large amounts of water might
regularly make rapid intrusions into Mars' upper atmosphere. To shed
light on these events, scientists analyzed data from the Mars-circling
Trace Gas Orbiter, which is part of the European-Russian ExoMars
program. The scientists focused on the way water was distributed up and
down the Martian atmosphere by altitude in 2018 and 2019. (1/9)
Virgin Galactic Enters
Its Next Phase (Source: Seeking Alpha)
Virgin Galactic appears to have made it through initial
post-IPO/post-SPAC skepticism. The management team have worked the
analyst community to good effect, securing lofty price targets amongst
tier-1 investment banks. The company is now in a period of relative
capital-markets quiet before commercial operations begin. We think that
approaching commercial launch, the stock will be driven by sentiment,
spaceplane construction milestones, and degree of interest in ticket
sales.
We have no reason to expect sentiment alone to fall. Space as a concept
will we think continue to be marketed heavily through the next couple
years, not least because NASA will need public support for its big
spending SLS rocket, its Artemis moon program and so on. They don't
quite have to sell war bonds to fund these things - Congress will
supply money - but it makes Congress' life easier if there is public
support behind all things space. It is no coincidence that if you walk
around toy stores right now - physical and virtual - space has arisen
as a theme more than at any time we can remember since the Apollo and
Shuttle eras. (1/13)
Two New Satellites Will
Launch This Year to Track Earth's Rising Oceans (Source:
Space.com)
Two new satellites will provide more detailed information about rising
sea levels and other ocean changes on Earth. Launching in November, the
Sentinel-6/Jason Continuity of Service mission (Jason-CS) will be the
longest-running Earth observation mission dedicated to studying the
rising oceans. The spacecraft will provide the most sensitive water
level measurements as it reveals details about rising oceans, helping
to build nearly 40 years of sea level records.
A joint U.S.-European satellite mission, S6 follows in the footsteps of
a trio of missions (TOPEX/Poseidon and Jason-1, Ocean Surface
Topography/Jason-2, and Jason-3) that have measured how sea levels have
risen over the past 30 years. The preceding spacecraft revealed that
Earth's oceans rose by an average of 0.1 inches (3 millimeters) in the
1990s, increasing to 0.13 inches (3.4 mm) today. (1/12)
SpaceX Just Blew Up a
Starship Tank on Purpose (Source: Teslarati)
Before dawn on January 10th, SpaceX technicians and engineers
intentionally blew up a miniature Starship tank in order to test
recently-upgraded manufacturing and assembly methods, likely to be used
to build the first Starships bound for flight tests and orbit. SpaceX
CEO Elon Musk quickly weighed in on Twitter later the same day,
revealing some crucial details about the Starship tank test and
effectively confirming that it was a success. While somewhat
unintuitive, this is the second time SpaceX has intentionally destroyed
largely completed Starship hardware in order to determine the limits of
the company’s current methods of production and assembly.
Most notably, on November 20th, SpaceX is believed to have
intentionally overpressurized the Starship Mk1 prototype in a very
similar – albeit larger-scale – test, destroying the vehicle and
sending its top tank dome flying hundreds of feet into the air. It’s
generally believed that SpaceX (or perhaps even just Musk) decided that
Starship Mk1 was not fit to fly, leading the company to switch gears
and deem the prototype a “manufacturing pathfinder” rather than the
first Starship to fly – which Musk had explicitly stated just a few
months prior. (1/12)

The Oldest Material on
Earth Has Been Found in a Meteorite (Source: WESH)
A new study of presolar grains from the Murchison meteorite recovered
in Australia has revealed "the oldest solid materials ever found, and
they tell us about how stars formed in our galaxy. They're solid
samples of stars." The meteorite was recovered in 1969 and presolar
grains were isolated from it. "It starts with crushing fragments of the
meteorite down into a powder," said Jennika Greer, study co-author and
a graduate student at the Field Museum and the University of Chicago.
"Once all the pieces are segregated, it's a kind of paste, and it has a
pungent characteristic. It smells like rotten peanut butter."
Dissolving the paste in acid reveals the presolar grains, allowing the
researchers to determine their age and the type of star they once
belonged to. The researchers were able to measure the exposure of the
grains to cosmic rays, highly energized particles zipping through our
galaxy. Many of the grains recovered were between 4.6 and 4.9 billion
years old, while others were older than 5.5 billion years.
They also learned that seven billion years ago, more stars began
forming. "We have more young grains than we expected," Heck said. "Our
hypothesis is that the majority of those grains, which are 4.9 to 4.6
billion years old, formed in an episode of enhanced star formation.
There was a time before the start of the solar system when more stars
formed than normal." Astronomers have argued about the rate of star
formation. Some believe it's steady and unchanging, while others
believe there are peaks and dips. (1/13)
Rand Study: Air Force
Should Pick Three Launchers (Source: Space News)
An independent study concluded the U.S. Air Force should support three,
rather than two, launch companies in the near future. The study by the
Rand Corporation does not recommend that the Air Force change its
decision to award national security launch contracts to just two
providers later this year, but concludes that the Air Force should find
a way to keep a third company in the market in the event of delays in
development of new vehicles. Four companies are competing for the
contracts, three of which are offering new launch vehicles. The report
said that historical data suggests that the first launches of those
vehicles could slip by a year or more. The Rand report also noted that
uncertainty about the size of the commercial launch market could
warrant keeping a third company in the mix. (1/13)
