[fornadablog.blogspot.com], SpaceX Falcon 9 flameout leaves commercial satellite in wrong orbit - Register
The Falcon 9 rocket from upstart rocket firm SpaceX, which lifted off yesterday with supplies for the International Space Station, will deliver those supplies successfully following loss of an engine during launch. However a commercial satellite which was also aboard the rocket has been placed into a lower orbit than planned as a result of the mishap.
As we previously reported, the nine-engined Falcon first stage suffered an engine failure as it climbed towards space, with launch video giving the impression that one of the Merlin rockets had lost its nozzle. The Falcon is designed to carry out its mission even having lost an engine, and the flight path was duly adjusted. The Dragon capsule with supplies for the International Space Station was successfully sent on its way and is expected to reach the ISS without trouble.
However the rocket also carried a satellite belonging to sat-tracking firm Orbcomm. The plan was that after the Dragon had departed from the Falcon second stage, the second stage would fire again and place the Orbcomm bird into its intended orbit.
Unfortunately it appears that the engine loss earlier in the flight meant that by the time the Dragon was released the Falcon could no longer conduct the necessary second burn due to flight-safety constraints intended to protect the ISS. Orbcomm said in a statement issued last night:
Due to an anomaly on one of the Falcon 9’s first stage engines, the rocket did not comply with a pre-planned International Space Station (ISS) safety gate to allow it to execute the second burn. For this reason, the OG2 prototype satellite was deployed into an orbit that was lower than intended.
It would appear that had the planned burn taken place, the Falcon second stage, the satellite, or other parts of the launch stack might have wound up on a flight path which would have potentially endangered the ISS and the 'nauts living aboard it.
Orbcomm says it is investigating the possibility of getting its satellite into the right place using its own onboard propulsion. Even if this can be achieved, however, it will be unsatisfactory as a satellite's own fuel must be sparingly eked out over its operational lifespan to maintain it in orbit. Using up a lot of it before even beginning operations is liable to mean a short working life for the Orbcomm bird.
While SpaceX can justly plume itself on the resilience of the Falcon 9 - which is the only rocket now flying able to carry on with a mission after suffering a first-stage engine failure during launch - the rocket firm can't claim that the launch was fully successful. ®

Question by Matthew D: How much is "a little water" for oven baking chicken? I have a recipe I'm going to try. I shall cook three boneless, skinless chicken breasts in the oven in a glass baking pan without the use of foil. The recipe states that I should ad a 'little water' before putting them in the oven. What does that mean? Does it mean simply cover the bottom of the pan with water? How much should I use? Thanks. Best answer for How much is "a little water" for oven baking chicken?:
Answer by °ΤΘΜ° Answer by TX2step Answer by Nikki P
I think your intuition is correct, maybe a few tablespoons more than just enough to cover the bottom of the pan.
About 1/4" water, but I'd put the chicken on a rack, so that it isn't sitting in the water. I've never used water with chicken, but do it for meat - and STILL cover tightly with foil - just opening the last 15 min. or so
I sometimes add about 1/4 cup of water to the pan when I am doing chicken. The water evaporates pretty fast but what it helps is to render out the fat and helps prevent sticking. Since you are using boneless, and skinless breasts the water will help keep the moisture as the boneless skinless breasts have a tendency to dry out pretty quickly. Watch them. If it seems like they are beginning to get done sooner than expected turn down the heat a bit. Since you are using glass baking pan I would turn it down about 25 degrees anyway.
