I don't think there are any 'vanilla' exsurgents. Maybe the critters in Mind the WMDs? But every instance I've seen of exsurgents has been different from the last, so pick your favorite book or movie and steal liberally. Launching a missile would probably kill any biomorphs on board, as well as possibly causing major damage to your goods. They run about 7 km/s, which is around mach 20. I'm sure given the technology at the time, there are probably some pretty sweet missiles with all sorts of anti-detection equipment on board, so locating this sort of gear could be the easiest solution. The railgun solution is more amicable to biomorphs, but not inline with canon. Following what's described in (iirc) The Case for Mars, building a giant coil gun under Mt. Killamajaro could be a pretty cost-effective way of launching stuff into space. Modify it to ramp up the speed and you could probably match the ICBM without squishing all your meatbags with the gs (plus you can stow more stuff in it). However, you need a lot more power and you'll still be a loud, hot target. Another option is the 'mysterious benefactor' trick. As the GM, you set it up so the group somehow gets information from a dark and mysterious agent who either passes on a passcode, or says that this route will be safe at this time. No matter how you cut it, the party now has to deal with the fact that someone else clearly knows that they're up to and is interested in it, for whatever reasons. Also worth mentioning, the amount of mass you're sending up is important. If you're just sending up a few stacks and a DVD, you can make do with a very small, fast rocket without doing much work. If you're sending up five biomorphs and your grandmother's bureau, you're talking about something akin to the Saturn V rockets in regards to acceleration if not size.

Well that's the thing, I think in ease of escape it'd go: Infomorph Synthmorph Biomorph So if you wanted to bring physical items back as the OP is suggesting your options are launch payload then farcast somehow, or unscrew your synthmorph head and toss that in there with the payload. }: ) Hmm there's the challenge, getting biomorphs off at least completely intact anyway. If you don't want to just cut off your head and cryo it offworld it looks like it's good old acceleration gel suspension for you. From Wiki's Liquid Breathing article, space travel subsection (too busy to dig up direct sources), "Liquid immersion provides a way to reduce the physical stress of G forces. Forces applied to fluids are distributed as omnidirectional pressures. Because liquids cannot be practically compressed, they do not change density under high acceleration such as performed in aerial maneuvers or space travel. A person immersed in liquid of the same density as tissue has acceleration forces distributed around the body, rather than applied at a single point such as a seat or harness straps. This principle is used in a new type of G-suit called the Libelle G-suit, which allows aircraft pilots to remain conscious and functioning at more than 10 G acceleration by surrounding them with water in a rigid suit." Seems you can manage about 15 to 20 G that way especially if your biomorph is designed to handle more G than usual. Higher if you fill all your body cavities with liquid.

Remember the Kimanjano beanstalk. You can always climb.

Who's to say they need to get off the planet? They could have come down with a broken down rocket that could get whatever they came down for off the planet plus their egos in some Spares. Those seem light and small enough to fit in a weak off world ride.
