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)[reply]

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)[reply]

Dymu4947, if you can create a history section with some background on the mission (with citations), go for it. — Huntster (t @ c) 05:07, 16 March 2018 (UTC)[reply]

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)[reply]

The satellite was not built by NG, but by Orbital Sciences (Orbital ATK), which was well-after bought by NG. Regardless, I noted its construction on the page. — Huntster (t @ c) 02:05, 15 October 2018 (UTC)[reply]
