Astroscale, a Singapore-based developer of space debris removal services, has raised $50 million, led by INCJ and joined by SBI Investment and Mitsubishi Estate Co.

Why it matters: There are an estimated 750,000 pieces of space debris at least one centimeter long, and that poses a major danger for the growing number of commercial space companies — particularly those focused on low Earth orbit satellite clusters.

Bottom line: "The company is currently working on its first debris capture demonstration mission, which is scheduled to launch in early 2020. [It] will consist of two spacecrafts, a Chaser and a Target, stacked together. The Chaser will repeatedly release and capture the Target in a series of demonstrations, including rendezvous and docking, and proximity operations." — Annamarie Nyiradi, Via Satellite

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

The New York Times editorial board has endorsed Sens. Elizabeth Warren and Amy Klobuchar for president, in a decision announced on national television Sunday night.

Why it matters: The board writes in its editorial that its decision to endorse two candidates is a major break with convention that's intended to address the "realist" and "radical" models being presented to voters by the 2020 Democratic field.

Senators will almost certainly get to vote on whether or not to call impeachment witnesses. The resolution laying out the rules of the trial, which will be presented Tuesday, is expected to mandate that senators can take up-or-down votes on calling for witnesses and documents.

Yes, but: Those votes won't come until the House impeachment managers and President Trump's defense team deliver their opening arguments and field Senators' questions.

Trump officials say they feel especially bullish about one key argument against calling additional impeachment witnesses: It could compromise America's national security.

The big picture: People close to the president say their most compelling argument to persuade nervous Republican senators to vote against calling new witnesses is the claim that they're protecting national security.
