PERIAPSIS=Perigee (Altitude in KMs) If OBJECT_NAME="TBA - TO BE ASSIGNED", then it has not been added to Satellite Catalog (SATCAT) yet. (Only 53 objects so far . . . diff processes). The equivalent SATCAT API query to the GP one above is: https://www.space-track.org/basicspacedata/query/class/satcat/predicates/norad_cat_id,object_id,PERIGEE,RCS_SIZE,decay,object_name/object_id/~~1982-092/format/html/metadata/true/orderby/norad_cat_id …

For clarification, there were already three objects on this launch cataloged prior to the ASAT event: 13552, 13553, and 42060 (which has already decayed). See our API documentation for the legend to decipher column names: https://www.space-track.org/documentation#api-restRulesAPIClasses … Epoch=Time(Zulu) object measured

It looks like 120 objects released so far https://www.space-track.org/basicspacedata/query/class/gp/predicates/tle_line0,tle_line1,tle_line2/object_id/~~1982-092/format/html/emptyresult/show/metadata/true/orderby/tle_line1 …

On Monday, 7 June, starting at 1900UTC, all space-track websites will be temporarily unavailable for up to 4 hours of maintenance. The 18th Space Control Squadron will continue spaceflight safety screenings and resolve any high priority events directly.

Yes, we know that the TIP coords (lat 22.2, long 50.0) plot in Saudi Arabia. That was the last place that the @18SPCS computer system recorded it. Operators confirm that the rocket actually went into the Indian Ocean north of the Maldives. We just report the data, folks!

We believe the rocket went down in the Indian Ocean, but are waiting on official data from @18SPCS

Everyone else following the #LongMarch5B re-entry can relax. The rocket is down. You can see all relevant information and updates here on Twitter/Facebook, so there is no need to keep visiting the space-track dot org website.

Yes, it is the same +/- 60 minute uncertainty window as the last TIP. This is difficult to predict and not an exact measurement.

Latest TIP (as of 2021-05-09 0000Z) for CZ-5B (#LongMarch5B) (48275 / 2021-035B) shows projected re-entry at 2021-05-09 0211(UTC) +/- 60 minutes at latitude 35.9, longitude 24.4 (Mediterranean Basin) At 7.8 km/s, just 1 minute diff in the time of reentry =470 km diff in final loc

#LongMarch5B Update from @18SPCS: Next TIP update expected around Midnight UTC (0000Z), about 2 hours prior to predicted re-entry. We will post it here, on our login page, and facebook as soon as we get it.

We have ceased new accounts so we can prioritize space-flight safety data exchange between @18SPCS and current Satellite Owner/Operators. Even though the world is focused on #LongMarch5B, we must continue to help protect the space environment. #SpaceFlightSafety #TeamSpace

Space-Track is temporarily suspending new account creation. All relevant re-entry information is displayed on the login page, so there is no need to log in to see more. We will continue to post TIPs to the login page and Twitter/Facebook as we receive them.

Notice the uncertainty window of +/- 60 minutes. At 7.8 km/s, just 1 minute early/late in the time of reentry = 470 km difference in the final location. This a PREDICTION, not an exact measurement. @18SPCS will not know the precise location until AFTER it has already landed.

Latest TIP (as of 2021-05-08 2016Z) for CZ-5B (#LongMarch5B) (48275 / 2021-035B) shows projected re-entry at 2021-05-09 0204(UTC) +/- 60 minutes at latitude 41.6, longitude 350.7 (North Atlantic) NOTE: Getting closer to re-entry, but still not a precise time or location.
