3. H-2A • IGS Optical 5

(For some people, including GMT, it appears, this will be on the 26th, but it's the 25th for me)

Launch window: 0100-0300 GMT on 26th (9:00-11:00 p.m. EDT on 25th)

1. Soyuz • ISS 42S

Launch time: 1942 GMT (3:42 p.m. EDT)

Launch site: Baikonur Cosmodrome, Kazakhstan

2. Soyuz • Galileo FOC-2

Launch window: 2146:18 GMT (5:46:18 p.m. EDT)

Launch site: ELS, Sinnamary, French Guiana

An Arianespace Soyuz rocket, designated VS11, will launch on a mission from the Guiana Space Center in South America.

Arianespace will oversee the launch. Delayed from November, December and March 26. [March 9]

March 28-

1. 28PSLV • IRNSS 1D

Launch time: 1149 GMT (7:49 a.m. EST)

Launch site: Satish Dhawan Space Center, Sriharikota, India

India’s Polar Satellite Launch Vehicle (PSLV), flying on the PSLV-C27 mission, will launch the IRNSS 1D navigation satellite. The payload is the fourth spacecraft in the Indian Regional Navigation Satellite System, which aims to improve positioning services over India and neighboring regions. Delayed from December, January and March 9. [March 19]

The next confirmed launch after that is the April 10 launch of SpaceX CRS 6 on a Falcon 9. There is also a launch of a Russian earth observation satellite, but this is TBD and just happens to be around this area of the Spaceflight Now list. Plus, it is a Plesetsk launch, so it probably will not be streamed.

By the way, are Dombarovsky Dnepr launches livestreamed? If anybody wants to research that, the company that launches Dneprs is ISC Kosmotras.

Also there's a Chinese launch planned 'before the end of the month', probably on the 31st. CZ-3C with the first phase 2 Beidou sat, and new YZ-1 upper stage.

No, unfortunately.

[LordFerret]

Too bad none of these launches is for a new telescope or other such scientific equipment.

Google Translate works fine.

Yep, that's right

BTW, will the Delta4 launch be streamed?

[Lilleman]

The Delta IV launch should be streamed here.

Thanks a lot!

Launch in 10 minutes.

[RocketPilot573]

Launch in 1 minute!

Launch in 10 minutes.

Thanks, just made it.

The angle threw me off, looked like an Dela heavy with add on SRB boosters, as in very kerbal.

[RocketPilot573]

This rocket seems quite fast... Mach 1 in 48 seconds?

[Dkmdlb]

Is the Japanese launch going to be streamed? Anybody have a link?

Also, anybody have a link to the ULA launch video?

*EDIT* I found the ULA launch:

You lucky Americans.

There won't be a livestream either for the Dnepr launch, nor for the H-2A one. However, I aksed it on Twitter a few hours ago and SpaceFlight101 said that they will post the link to an amateur livecast of the H2A launch shortly. (https://twitter.com/Spaceflight101/status/580750785459408896)

[Frida Space]

And here goes the Dnepr with KOMPSAT 3A....

Next launch in ten minutes;

They have TWRs greater than 1, right? That's more than 10 m/s^2. Speed of sound is ~340.29 m/s. Assuming 10m/s^2, then it would take ~34 seconds. So, no. Not particularly fast... Except for the fact that all rockets need to go fast.

[PlonioFludrasco]

You mean greater than 2: TWR=1 means thrust = weight, and the rocket wont leave the pad.

[Whirligig Girl]

You mean greater than 2: TWR=1 means thrust = weight, and the rocket wont leave the pad.

Greater than 1 means it will leave the pad, because thrust > weight. Saturn V had TWR of 1.2 on liftoff IIRC.

And yet there's lots of people in the photo who just don't give a rat's ass. -.-

Yes you are right, the TWR=2 is to have 10 m/s^2 of acceleration.
