CRS-15 SpaceX Rocket Launch

SPX-15 was scheduled as an "instantaneous launch" which means that if it didn't go off as planned on June 29th at Kennedy Space Center, the NASA Launch would have been delayed until July 1st (no pressure, right?). Well the good news is, the Falcon 9 made it off the pad at exactly 5:42:42 a.m. EDT.   The capsule (known as Dragon) then separated from the rocket nine minutes later and is scheduled to dock with the International Space Station (ISS) on July 2nd.

Dragon is delivering almost 3 tons of supplies, equipment, and the following science investigations for the ISS:

  • Investigation on cellular biology in microgravity
  • ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS), an Earth science instrument studying plants and water availability
  • A physical sciences study on soil and sediment to enable U.S. National Laboratory research

Dragon will then return to Earth in about a month, carrying 2 tons of cargo from the ISS. Not only is this mission important because of the cargo going to and from the ISS but it also serves as a great opportunity to test the previously flown upper stage coasting ability.  To test this ability, it will orbit four times around the earth until it ultimately splashes down somewhere in the Atlantic Ocean. That's right, no booster landing with this SpaceX rocket launch but this will let Space-X realize the possibility of direct insertion into geostationary orbit.

GO Space Force

The sixth Advanced Extremely High Frequency Satellite launched today from Cape Canaveral, FL.  Dubbed AEHF-6, this mission again used the might Atlas V 551 rocket to carry on the tradition of putting strategic, reliable and secure communications in place for the U.S. Armed forces. While this was the 134th successful launch for United Launch Alliance (ULA), it was the 1st for Space Force. Now that the payload is off the ground, we only have roughly five hours till deployment. We won't get to see the deployment as ULA will not televise/broadcast that portion of the mission because, lets not forget, it is a National Defense satellite, but it's all still exciting non the less. Lots of rockets take off from the East Coast of Florida but arguable non more exciting than this beautiful powerhouse from ULA. With COVID-19 social distancing efforts ramping up, we're not sure what will become of other launches in April/May but we'll be certain to keep you posted. ULA is to be comme...

TOP SECRET X37-B Takes Flight... Again

The 45th Space Wing put the X37-B back into play on Sunday.  A flawless launch (excluding weather) marked the beginning of yet another undetermined period of orbit for this spectacular craft. Most outlets are talking about the same thing, an energy beam experiment which is onboard this mission that is supposed to collect and send concentrated solar energy back to earth in the form of microwaves... YAWN.  This craft has so much more potential and 'wireless charging' is the detail they choose to share. This sort of sounds like the 'diversion topic' so outlets don't start talking about some of the other likely uses for such a craft. If you've been following the X37 project you likely know it stays up for very long periods of time: OTV-1 was up for 225 days OTV-2 was up for 469 days OTV-3 was in orbit for 675 days OTV-4 launched in 2015 and spent 718 days in space!! OTV-5 which just returned in October of last year after a whopping 780 days in space One can only sur...

Es'hail 2 Takes Flight

Amateur radio enthusiasts from Brazil to Thailand should be excited as they will soon have access to 2 “Phase 4” amateur radio transponders operating in the 2400 MHz and 10450 MHz bands. A 250 kHz bandwidth linear transponder intended for conventional analogue operations and an 8 MHz bandwidth transponder for experimental digital modulation schemes and DVB amateur television (as reported by AMSAT-UK).The general public (and launch photographers) also had reason to celebrate as Es'hail 2 broke a long string of night launches at Kennedy Space Center. The Visitors Complex seemed excited about this as well based on the fact that they allowed guests to view the launch from the Saturn V Center without any additional fee above or beyond the cost of daily admission.  Having said that, I really hope they bring back some VIP viewing experiences  as I think those tickets really drive excitement about the process and make the day more special to those will to pay for premium experien...
