Companies are trying to capitalize on the threat of space junk with new technology to clean it up, but it's not clear who will pay for the service.

Why it matters: Today, thousands of pieces of space junk — ranging from tiny fragments of destroyed satellites to spent rocket bodies and defunct spacecraft — orbit around Earth, threatening operational satellites and astronauts.

  • As thousands of new satellites are slated for launch in the coming years, operators are desperate to find ways to track, remove and prevent the creation of more rogue debris in orbit.
  • The market for in-orbit satellite services is projected to reach about $4.5 billion by 2028, according to Northern Sky Research.

Driving the news: The European Space Agency recently signed a contract with ClearSpace to remove a piece of a rocket left in orbit on a mission launching in 2025.

  • Astroscale is designing a method to pull junk from space. It plans to launch a test mission in 2020.
  • Northrop Grumman launched a vehicle in October on a journey to link up with a satellite that's low on fuel to help keep it functioning in orbit past its expected end date.
  • Satellite internet company OneWeb is planning to affix grappling tech made by Altius Space Machines to its small satellites in low-Earth orbit to make it easier for them to be deorbited should they fail.

The catch: Experts agree space junk is a major threat to keeping space usable and open for nations and companies around the world, but it's not clear who is or should be responsible for cleaning it up, complicating the business case for these companies.

  • "There is no agreement as to who pays for debris removal," Victoria Samson, of the Secure World Foundation, told Axios. "You could argue that space being a public good, it should be the government that pays for it."
  • Some companies are also banking on the idea that Amazon, SpaceX, OneWeb and others will succeed in launching thousands of new satellites and have the forethought to want to deorbit any failed satellites quickly.

Yes, but: There are also major technical challenges around building and launching any of these new systems.

  • Linking up with a dead satellite in orbit will be a risky procedure that needs to be exact in order to make sure the system doesn't create more debris in the process.

Go deeper: Yes, there really is a lot of space junk

Sens. Tim Kaine and Susan Collins are privately pitching their colleagues on a bipartisan resolution censuring former President Trump, three sources familiar with the discussions tell Axios.

Why it matters: Senators are looking for a way to condemn Trump on the record as it becomes increasingly unlikely Democrats will obtain the 17 Republican votes needed to gain a conviction in his second impeachment.

Judge Merrick Garland, President Biden’s nominee for attorney general, has tapped Anthony Coley, an Obama-era Treasury Department official, to serve as a senior adviser and to lead public affairs at the Department of Justice, according to people familiar with the matter.

Why it matters: As the public face of the DOJ, Coley will help explain — and defend — the department's actions, from sensitive cases to prosecutorial decisions, including the investigation into Hunter Biden.

President Biden's acting Attorney General Monty Wilkinson issued a memo on Tuesday to revoke the Trump administration's "zero tolerance" immigration policy, which separated thousands of migrant children from their families at the U.S.-Mexico border, AP first reported.

Driving the news: A recent report by Justice Department Inspector General Michael Horowitz emphasized the internal chaos at the agency over the implementation of the policy, which resulted in 545 parents separated from their children as of October 2020.
