Math issue with radiometry? edit
Text says the instrument sends 2e10 photons and gets 12 photons back. However, for the orbit altitude and mirror size in the article, a Lambertian reflector on the ground would require about 1000 times as many photons. Also, 1e10 photons per pulse @ 10 kHz for six lasers is only 2 W total - an unlikely small amount of power. Methinks the "20 trillion" is wrong. The original web reference no longer exists. 128.149.241.54 (talk) 20:34, 16 October 2023 (UTC)

Delayed Launch edit
Hi, what do you guys think about adding a section about the delayed launch of IceSAT-2? It has been delayed past the original scheduled launch and has run significantly overbudget. There doesn't seem to be anything here on that part of the mission's story. Dymu4947 (talk) 03:31, 16 March 2018 (UTC)
More project development history edit
Why no mention that the satellite was designed and built by Northrop Grumman in Gilbert, Arizona?
To me, that's an important piece of the "Project development." 2600:8800:785:1300:C23F:D5FF:FEC4:D51D (talk) 09:43, 23 September 2018 (UTC)
