Satellite Database Update: More than 3,300 Active Satellites Orbiting the Earth

An updated version of the UCS Satellite Database, which includes launches through December 31, 2020, is now available on the UCS website. This update includes the addition to the database of 651 satellites and the removal of 66, for a total of 3,372 active satellites. Commercial satellites continue to take a larger share of space; currently 78% of US satellites are commercially-owned. With this version of the Database, Starlink has more than 900 satellites in orbit, or 26% of the operational satellite population.

The TPNW, Equity, and Transforming the Nuclear Community: An Interview with Nuclear Scholar Dr. Aditi Verma

In anticipation of the entry into force of the landmark Treaty on the Prohibition of Nuclear Weapons (TPNW) on Friday, I had the honor of corresponding with Dr. Aditi Verma, a Stanton Nuclear Security Postdoctoral Fellow at the Harvard University Belfer Center’s Project on Managing the Atom and the International Security Program.  Dr. Verma, who holds undergraduate and doctoral degrees in Nuclear Science and Engineering from MIT, is broadly interested in how nuclear technologies can be designed in collaboration with publics such that traditionally excluded perspectives can be brought into these design processes. She’s one of the five authors of the essay, “A call for antiracist action and accountability in the US nuclear community.”

Some pretty good work by Congress on missile defense this year

The Congressional defense budget process is entering its conclusion, though battles remain. Despite little to show for it, the overall budget for missile defense continues to be robust. For example, the Senate appropriators met last week and added $1.2 billion above the Trump administration’s budget request for missile defense, including an additional $532 million for upgrades and six more boosters for the beleaguered Ground-based Midcourse Defense system, and added $222 million to fund program to replace the recently canceled Redesigned Kill Vehicle program. That is an unfortunate waste of tax dollars.

However, in other areas Congress—in particular the House—made a number of useful and positive corrections to the administration’s $9.4 billion missile defense budget request. The House also put several sensible new missile defense policies in place that deserve support. Read more >
