A private astronaut explains how Axiom plans to replace the International Space Station and potentially save NASA billions per year
  • NASA wants to deorbit the International Space Station before the end of this decade.
  • The space agency and Congress want a commercial replacement in orbit before the ISS is trashed in the Pacific Ocean.
  • Axiom Space, a startup founded by a former NASA executive, is working to build, launch, and assemble "AxStation," an all-private outpost.
  • Michael López-Alegría — a former NASA astronaut and Axioms' vice president of business development — says use of the new station would cost a fraction of the $3.5 billion NASA spends each year.
  • "That just makes good economic sense," López-Alegría told Insider, noting NASA could use the savings on deeper-space exploration of the moon, Mars, and beyond.

NASA is extending Mars and Jupiter missions, citing notable success

Juno and InSight have 'increased our understanding of our solar system,' NASA said

Citing discoveries that have "produced exceptional science," NASA has decided to add several years to two of its planetary science missions: the Jupiter Juno mission and the Mars InSight lander.

After a lengthy review process, which can be found here, the space agency concluded that both missions have "increased our understanding of our solar system, as well as spurred new sets of diverse questions."

"The Senior Review has validated that these two planetary science missions are likely to continue to bring new discoveries, and produce new questions about our solar system," said Lori Glaze, director of the planetary science division, in a statement.

Serious Science™ at last:
French wine returns to Earth after a year in space

Image

CAPE CANAVERAL, Fla. (AP)– 12 bottles of French Bordeaux wine and pieces of grapevine that spent a year orbiting in space returned to Earth.

SpaceX’s Dragon cargo capsule undocked and and aimed for a splashdown in the Gulf of Mexico off the coast of Tampa. The Atlantic Ocean was initially planned as the landing spot but due to poor weather the capsule ended up in the Pacific.

Each bottle was carefully packed inside a steel cylinder to prevent any breakage.

Space Cargo Unlimited, a Luxembourg startup behind the experiments, wanted the wine to age for a year in space.

None of the bottles will be opened until the end of February. The company will open a bottle for a wine tasting in Bordeaux by some of France’s top connoisseurs and experts.Lots of chemical testing will follow as researchers are eager to see how space altered the sedimentation and bubbles.

According to Nicolas Gaume, the company’s CEO and co-founder, agricultural science is the point of this experiment.

“Our goal is to tackle the solution of how we’re going to have an agriculture tomorrow that is both organic and healthy and able to feed humanity, and we think space has the key,” said Gaume.

Remember the InSIght Lander that landed on Mars a couple years ago? It was supposed to drill down under the surface and stick a probe in.
Maybe you remember this image?

Well, apparently it never really worked the way they hoped.

Mars digger bites the dust after 2 years on red planet
NASA declared the Mars digger dead Thursday after failing to burrow deep into the red planet to take its temperature.

Scientists in Germany spent two years trying to get their heat probe, dubbed the mole, to drill into the Martian crust. But the 16-inch-long (40-centimeter) device that is part of NASA’s InSight lander couldn’t gain enough friction in the red dirt. It was supposed to bury 16 feet (5 meters) into Mars, but only drilled down a couple of feet (about a half meter).

Following one last unsuccessful attempt to hammer itself down over the weekend with 500 strokes, the team called it quits.

“We’ve given it everything we’ve got, but Mars and our heroic mole remain incompatible,” said the German Space Agency’s Tilman Spohn, the lead scientist for the experiment.
The mole’s design was based on Martian soil examined by previous spacecraft. That turned out nothing like the clumpy dirt encountered this time.

Report: U.S. military space programs at risk of losing domestic sources of key components

WASHINGTON — U.S. military satellites and missiles continue to rely on customized hardware and niche components that are no longer manufactured domestically, the Pentagon said in a report to Congress released Jan. 14.

These programs need to invest in new technology and qualify new suppliers to ensure they have access to domestic sources, said the Defense Department’s Fiscal Year 2020 Industrial Capabilities Report, which the Pentagon must submit annually to congressional defense committees.

“The DoD space industrial base remains a niche market with very specialized and capital-intensive requirements that are not efficiently managed through individual program investments,” the report said.

Many current and planned systems rely on dated technology and practices, as well as fragile or foreign sources, said the report. “Reliance on foreign sources for critical technologies, competition from subsidized lower-cost imports, and erratic demand from the national security space enterprise will erode essential space capabilities and critical skills, and threaten future access to space qualified domestic industrial sources.”

The 181-page report — which covers every sector of the defense industry — was written by the office of Undersecretary of Defense for Acquistion and Sustainment Ellen Lord. The space portion of the report was put together by the Space Industrial Base Working Group, a team of Pentagon, NASA, Federal Aviation Administration and National Reconnaissance Office representatives. The group was created in 2017 after President Donald Trump issued an executive order directing federal agencies to probe vulnerabilities in the nation’s manufacturing and supply sources.

Other findings from the report:
  • There is limited domestic production capacity of precision gyroscopes used in military spacecraft, launch vehicles and missiles.
  • Military and NASA satellite programs need access to lower cost space-qualified solar cells. U.S. suppliers are developing more advanced cells but foreign competitors are producing high efficiency cells at lower costs.
  • The United States is an overall world leader in commercial space, but competitors such as China are rapidly expanding their commercial space industries.
  • Recent commercial market downturns have resulted in layoffs and skills gaps in the U.S. industrial base for traveling wave tube amplifiers, used to improve radio frequency spectrum access and increase bandwidth in military satellites. A sole domestic supplier competes with a single foreign source for production of all space qualified amplifiers.
  • The long-term impacts of the coronavirus pandemic on the space industry are still unclear. Potential areas of concern include a slowdown in capital expenditures and more rapid industry consolidation than originally anticipated.
  • The largest six prime defense suppliers are Lockheed Martin, Boeing, Northrop Grumman, Raytheon, General Dynamics, and BAE Systems. They collectively won 32 percent of all DoD contract obligations in 2019.
