Quick answer · as of 19 Jun 2026

A satellite rescue mission and Canadarm2 repairs are key highlights, alongside close orbital encounters and a pulsar record.

A bold satellite rescue mission has been rapidly organised to address a critical situation in orbit. The mission aims to recover a malfunctioning satellite, though details on the specific satellite and the nature of its malfunction remain under wraps. This operation underscores the increasing complexity and risk management required in satellite operations. For those tracking satellite movements, the Satellite Library provides comprehensive data on active satellites.

Canadarm2 Repairs Planned as CRS-34 Departs ISS

The International Space Station (ISS) is set to undergo maintenance as Canadarm2, the station's robotic arm, requires repairs. The departure of the CRS-34 mission has freed up resources and time to address the issue. Canadarm2 is crucial for docking operations and maintenance tasks on the ISS. The Spacecraft & Capsules section offers insights into the technology aboard the ISS.

Several close approaches have been recorded, with the most notable being between TIANHUI 5A and TIANHUI 5B, at a minimal distance of approximately 1.10 km. These events highlight the crowded nature of Earth's orbit, where thousands of active satellites and debris fragments coexist. The Debris Map visualises these interactions, providing a real-time overview of orbital congestion.

What to Watch

While no new launches are scheduled for the immediate future, the space community is closely monitoring the ongoing satellite rescue mission. Additionally, the pulsar spinning at a record 716 times per second continues to intrigue astronomers. For those interested in upcoming events, the Launch Schedule offers a comprehensive overview of future missions.

Frequently Asked Questions

What is the Canadarm2 used for?
Canadarm2 is a robotic arm on the ISS used for docking, maintenance, and assembly tasks. It plays a vital role in the station's operations.
How are close approaches in orbit managed?
Close approaches are monitored using tracking systems to predict potential collisions. Operators can manoeuvre satellites to avoid risks when necessary.
