The controlled deorbit maneuvers lowered the satellites’ perigee into dense atmospheric bands to ensure thermal destructive burn-up.
The LINK vehicle will decouple from the telescope after the multi-month propulsion campaign and use remaining xenon propellant reserves to lower its perigee for destructive atmospheric reentry.
SMILE will later move to a highly elliptical final orbit with an apogee of 121,000 kilometers and a perigee of 5,000 kilometers.
SMILE was inserted into a circular low Earth orbit at an altitude of about 700 km before heading to a highly elliptical, high-inclination orbit with a 5,000 km perigee and a 121,000 km apogee.
Blue Origin’s New Glenn 3 mission had a mission apogee of 460 km and a perigee of 460 km.
South Korea’s Perigee Aerospace and Firefly Aerospace have committed to using Esrange Space Centre for future launches.
Orion Integrity and the Artemis II crew completed a perigee raise burn.
Orion Integrity and the Artemis II crew completed a Perigee Raise Burn.
The Artemis II crew’s first rest period is split into two four-hour sleep periods separated by a wake period to monitor a perigee raise burn by the European Service Module.
Perigee Aerospace has signed an agreement to launch from the Esrange orbital launch complex.
Haven Demo completed its first perigee-lowering maneuver in about 14 minutes and reduced its altitude by 170 kilometers.
The Firefly Alpha second stage made a perigee-lowering burn at about 0140 UTC to 231 x 423 km x 123.1 deg.
Increased atmospheric density during Solar Cycle 25 raised atmospheric drag at perigee for highly elliptical spacecraft like Van Allen Probe A, lowering their apogees and accelerating orbital decay.
Orbital evolution plots for Viasat-3 F2 show its apogee and perigee ascending to geostationary altitude by early March 2026.
Perigee Aerospace signed an agreement in May 2024 to become Esrange’s first orbital launch partner with plans to conduct Blue Whale 1 rocket flights from Esrange.
Satellites 2026-023B through 2026-023J (NORAD 67675–67682) have apogee heights of about 511–514 km and perigee heights of about 484–487 km.
A spacecraft is in a low Earth orbit with perigee 345 km, apogee 591 km, and inclination 49.99°.
COSMOS 2600 (NORAD 67674, 2026-023A) has an apogee height of 329 km, a perigee height of 326 km, and an orbital eccentricity of 0.0002431.
During earlier Cluster reentries the satellites entered safe mode during their final perigee pass because their solar panels overheated when they dipped deep into the upper atmosphere.
Propellant was vented from the Falcon 9 second stage on Starlink Group 17-32, lowering the stage perigee to 110 km.
