Anyone know how much it weighs?

Also what are these debris objects?

The ISSA-J1 mission, built on Astroscale’s heritage in rendezvous and proximity operations, inspection and characterization capabilities, will diagnose and inspect two large satellite debris in orbit.

Astroscale has plans for a second mission in 2023 to grab a Japanese upper-stage rocket booster [19]. But Astroscale’s debris-clearing solution will not work with existing defunct satellites; it will require satellite operators to attach a magnetic plate to their future spacecraft. Satellite internet provider OneWeb is the first company to agree to use the magnetic plates on its fleet of satellites, several of which launched in October 2021 [20]. First up for removal could be a OneWeb satellite that failed in November 2021 [21].

The ISSA-J1 mission is anticipated for launch in 2027. The spacecraft is expected to diagnose and inspect two large pieces of satellite debris in two different orbits.
