NASA has launched that SpaceX’s Falcon 9 rocket – utilizing a flight-proven booster – will start the ~300 kg (670 lb) Imaging X-ray Polarimetry Explorer (IXPE) spacecraft no sooner than April 2021.
Intriguingly, IXPE used to be originally deliberate to start on Orbital ATK (now Northrop Grumman’s) Pegasus XL but NASA never followed through with a start contract. The circulate to SpaceX’s Falcon 9 rocket is probably going associated to the extraordinarily disruptive and dear start delays NASA’s Ionospheric Connection Explorer (ICON) spacecraft has suffered on the hands of its Pegasus XL rocket. Able to launching much less than 450 kg (1000 lb) to low Earth orbit, Pegasus XL has been fortunate to start yearly over the final decade or so and carries a ticket of at least $50M-$60M this day.
As a method to add to this: NASA says SpaceX can use a beforehand flown booster on this mission.
IXPE is a small satellite, but this start contract is much less than what NASA paid for for the nonetheless-pending Pegasus XL start of ICON ($56.3M in a 2014 contract). Take into tale that… https://t.co/sJlWVMHC5c

Limited rocket, enormous delays
Defying its small measurement, Pegasus XL used to be originally scheduled to start ICON in December 2017. Delayed by unspecified complications with start car hardware, the mission used to be pushed lend a hand an inexplicable 10 months to October 2018, the build additional concerns with the rocket again indefinitely scrubbed a start strive. In early 2019, the starting up used to be tentatively scheduled for Q2 2019, whereas – as of July – ICON is no longer anticipated to start sooner than September 2019.
All mentioned and executed, in the increasingly more no longer likely event that Pegasus XL is ready for start this September, the ICON spacecraft – ready for start since uninteresting-2017 – can had been delayed more than 21 months by complications with the rocket.
Again, for the small-scale performance of Pegasus XL, the rocket nonetheless carries a ticket of more than $50M – NASA’s ICON start contract used to be valued at more than $56M. Responsive to this, SpaceX has managed to sway NASA to start the small IXPE spacecraft on a flight-proven Falcon 9 at a charge of exact $50.3 million, without grunt the lowest Falcon 9 start contract charge ever publicized.
In most in vogue months, SpaceX executives absorb made comments indicating that Falcon 9’s default immoral stamp – likely assuming a flight-proven booster – is now as low as $50M. July eighth’s NASA start contract is the principle disclose confirmation of that exceptionally cheap pricing, likely moreover indicating that the immoral stamp for Falcon 9 is even lower for industrial customers with much less stringent requirements.
Barring an surprising contract between now and IXPE’s anticipated April 2021 start, the mission it will likely be the principle time that a dedicated flight-proven SpaceX rocket launches a scientific spacecraft for NASA. SpaceX’s next dedicated NASA start – the ESA-constructed Sentinel 6A spacecraft – is scheduled to no sooner than November 2020 and is vulnerable to flit on a fresh Falcon 9 booster.
In April 2019, NASA awarded SpaceX $69M for Falcon 9 to start the company’s Double Asteroid Redirect Take a look at (DART) – an asteroid-impactor spacecraft – no sooner than June 2021. IXME is SpaceX’s second NASA start contract have interaction of 2019.
In accordance to NASA, “IXPE will flit three blueprint telescopes with sensitive detectors able to measuring the polarization of cosmic X-rays, allowing scientists to resolution well-known questions on these turbulent environments the build gravitational, electric and magnetic fields are at their limits.”
